Hogan spent a whole lot of time developing technique that would discourage a hook. If the wind is on your left (I interpret this to mean left to right), you need to hit a draw/hook to get that visual feedback of a straight ball. Also, if you hit a straight ball, the wind makes it appear as a draw. If the wind is on your right (right to left) you hit fades into it that give you visual feedback of a straight ball. Hogan talked about not wanting his ball to even know it could go right to left. Just a guess.
